Gerry Conlon, wrongly jailed for a 1975 IRA bombing in which he had no part, died on June 21 at the age of 60. The case of the Guildford Four remains one the most famous miscarriages of justice in Britain – but more and more cases of wrongful imprisonment are coming to light around the world.

On June 18, it was widely reported that Jonathan Fleming, who in April 2014 successfully overturned his conviction for the murder of Darryl Alston in 1989, had begun a lawsuit against the City of New York for the 25 years he spent wrongly incarcerated.

It is alleged that prosecutors knowingly manufactured a case against Fleming, even dropping criminal charges against a key prosecution witness in return for false identification evidence. Fleming was on a family holiday in Disneyland at the time of the murder. He is now suing the city of New York for $162m.

An incredible story, we might think, but one that is becoming increasingly commonplace. And the growing awareness of cases like this is now fostering a global social movement to help innocent victims of wrongful convictions.
